Activation of phenol derivatives with a hypervalent iodine reagent promotes the formation of bicyclic and tricyclic products via a cationic cyclization process. The method allows efficient one-step syntheses of scaffolds present in several natural products and occurs with total stereocontrol, governed by 1,3 allylic strain interactions and by the configuration of the side chain double bonds.
用高价碘试剂活化酚衍生物可通过阳离子环化过程促进双环和三环产物的形成。该方法可以有效地一步合成存在于几种天然产物中的支架,并且可以通过1,3烯丙基应变相互作用和侧链双键的构型进行完全立体控制。
